IMPROVEMENT IN DOOR AND GATE SPRINGS.

Specification forming part of Letters Patent No. 116,196, dated June 20,1871.

To all whom it may concern:

Be it known that I, PHILIP KERN, of the city of Dayton, in the county ofButler and State of Ohio, have invented certain new and usefulImprovements in Door and Gate Springs, of which the following is aspecification:

My invention relates to a fastening device whereby the said spring maybe easily and cheaply attached to the said door and frame, and wherebysaid door and spring may be quickly removed from the door-frame and asquickly replaced.

In the accompanying drawing, Figure l is a side elevation ofsaloon-door, to which is attached a flat spring in the position which Iregard as novel, said elevation also showing the application of mydevice for attaching said spring to the door and frame. Fig. 2 is afullsized elevation, in perspective, of the front,

side, and end of my attaching device. Fig. 3 is a view, in perspective,of thefront, side, and end of one of the varieties of spring used by me.

General Description.

A A are, respectively, the right and left side pieces of the frame ofsaloon-door. B is the lintel or head-piece of said. door-frame, while 0is the sill or threshold of the same. E D H D is a slatted door, ofwhich E and H are, respectively, the right and left side pieces. D isthe top, and D the bottom of said door. This door swings upon hinges ofany'desired variety. For saloon-doors such hinges are pre:

ferred as will allow the door to be taken off from its hinges withoutunscrewing a part of each hinge. One simple style of such hinge is shownin Fig. 1 of drawing, the pivots of each hinge fastened to the sidepiece H being marked N, and the complimentary part of each tached to thelower part of A at a short distance from the end of said spring. Thisspring might be attached so that it would cross in a direction exactlythe reverse of what it now doesthat is, the top of S might be fastenedon the upper and inside portion of the frame A, and the bottom of S onthe lower part of the edge of the door nearest the frame A. The springis attached by any suitable fastening. The method of fastening I'findmost convenient is that shown in the drawing. I attach the upper pointof the spring in the door at K by a screw. Just below K I attach afastening (see Fig. 2) resembling a buckle. This fastening consists of aflat plate, T, having an arch or bridge, V, supported by shoulder X X,and raised high enough above the plate to allow the spring to be passedbetween said arch and the plate T. Plate T may be made light by castinga hole in the inside of the plate.

In plate T are bored holes for the reception of screws or nails. Thisfastening is attached to the edge of the door, immediately below thescrew K, by screws P P, so that the spring passes oier the flat piece Tand under the bridge V. To attach the lower end of the spring to sidepiece A I employ another of these fastenings, secured by screws at P P,

Claim.

What I claim as new is The spring S, when attached-at one end to thedoor or frame, while the other end passes under a bridge, V, whichresists torsion, but

permits longitudinal movement, substantially as described.
